Inerciální jednotka Hydrins

The IXBLUE (now Exail) Hydrins inertial navigation system is a high-tech marine navigation device. It is designed to accurately measure a vessel's movement and orientation, providing essential data for navigation, dynamic positioning, and other maritime applications.

The Hydrins IMU provides critical data such as heading, roll, pitch, acceleration, and angular rate. These parameters are essential for advanced navigation systems, autopilots, multibeam sonars, dynamic positioning (DP) systems, and hydrographic applications, enabling precise vessel attitude and position awareness even without GNSS signals.

The Hydrins IMU provides a complete set of motion and positioning data. This typically includes:

Heading (azimuth)
Roll (lateral tilt)
Pitch (longitudinal tilt)
Linear accelerations on all three axes
Angular rates on all three axes
Positioning and velocity data, often enhanced by integration with a GNSS receiver.

IXBLUE (now Exail) is globally recognized for its expertise in fiber optic gyroscope (FOG) technology. The Hydrins range of inertial navigation systems typically incorporates this FOG technology, which delivers very high accuracy, excellent reliability, and long service life, with no moving parts.

Key benefits of the Hydrins inertial measurement unit include:

High accuracy: Provides very precise motion and positioning data.Reliability: Its FOG technology is robust and ensures stable operation in demanding marine environments.Autonomy: Maintains accurate attitude and position awareness even during temporary GNSS signal loss.Easy integration: Designed to interface with a wide range of navigation systems and onboard equipment.

Yes, IXBLUE equipment is specifically designed for marine environments. The Hydrins IMU is built to withstand harsh sea conditions, including vibrations, shocks, temperature variations, and humidity, ensuring reliable and durable performance.

Inertial measurement units (IMUs) based on FOG technology, such as those from IXBLUE, are known for their low maintenance requirements. Thanks to the absence of moving parts, they offer high reliability and long operational lifespan, thereby reducing maintenance interventions.

An inertial measurement unit (IMU) operates by measuring the vessel's movements using internal sensors. It employs gyroscopes to detect angular rates (rotations) and accelerometers to measure linear accelerations. By integrating these measurements over time, the IMU continuously calculates the vessel's attitude (heading, roll, pitch), speed, and position, often fusing this data with GNSS for optimal accuracy.

The Hydrins IMU is a standalone inertial measurement unit capable of providing attitude and motion data. For absolute positioning and long-term accuracy, it is typically designed to be coupled with an external GNSS (GPS, GLONASS, Galileo, BeiDou) receiver. This integration combines the advantages of both technologies.

The exact physical dimensions and weight of the Hydrins inertial measurement unit are precise technical specifications that vary depending on the configuration or specific version of the model. This information is detailed in the official product datasheet, available from the manufacturer or your dealer.

Yes, IXBLUE (Exail) regularly releases software (firmware) updates for its inertial measurement units to improve performance, add new features, or ensure compatibility with emerging standards. These updates are typically available through the manufacturer’s or retailer’s technical support.

Thanks to the use of FOG technology with no moving parts and a robust design, IXBLUE Hydrins inertial measurement units are designed to provide a very long operational lifespan, often spanning several decades, with stable and reliable performance throughout their lifecycle.

For optimal performance, the Hydrins IMU must be installed on a stable and rigid surface, as close as possible to the vessel’s center of gravity or the point of interest for which measurements are required. It is also crucial to minimize vibrations and avoid heat sources or electromagnetic interference nearby.

The Hydrins IMU is typically mounted permanently on a mounting plate or rigid support, ensuring precise alignment relative to the vessel's axes (fore-aft, port-starboard, up-down). The product installation manual provides detailed instructions on mounting methods and alignment tolerances to ensure maximum accuracy.

Yes, like any professional equipment, the Hydrins inertial measurement unit is supplied with complete documentation, including a detailed installation manual. This manual contains all the necessary information for correct installation, including wiring diagrams, mounting specifications, and initial configuration steps.

Installing the Hydrins central unit requires basic tools for mechanical assembly and electrical wiring, such as wrenches, screwdrivers, and crimping or connection tools. Precision measuring tools (level, square) can help ensure perfect alignment. Specific requirements are detailed in the installation manual.

The Hydrins control unit is designed to integrate with a wide range of professional marine navigation systems, including advanced autopilots, mission management systems, electronic charting software, and dynamic positioning systems. Compatibility is ensured through the use of standard maritime industry communication protocols.

Yes, the Hydrins central unit is specifically designed to be connected and operate in synergy with an external GNSS receiver. This integration significantly improves long-term positioning and speed accuracy while leveraging the stability and robustness of inertial data in the short term.

IXBLUE Hydrins inertial measurement units (IMUs) typically support multiple communication interfaces to facilitate integration. These may include serial ports (RS232/RS422), Ethernet interfaces (for data and configuration), and potentially synchronization outputs. Specific data protocols (e.g., NMEA or proprietary formats) are defined in the technical documentation for each model.

Yes, thanks to its communication interfaces such as Ethernet or serial ports, the Hydrins unit is designed to integrate easily into an existing onboard network. This allows efficient distribution of motion and positioning data to all ship systems and equipment that require it.
